This scroll is from that scheming dryad Rynthariel, Keymaster of the Talon Den on Stonetalon Peak.
She'll not be making any more contact with the messenger you looted this from, heh, but we must stand our ground here. The Horde will not tolerate her outrunners here.
<name>, travel to the Talon Den. Kill Rynthariel, and then put up a symbol for all to see. Take this Horde flag, <name>. Put it up in the Talon Den so that they will not be so rash as to send another messenger through our territory again.
You're a tough one! Ridding the Den of Rynthariel is a major step, <name>. They will be slow to regroup, and so we can count on less Alliance runners in the Barrens. They will think again before sending another this way.
